Hello, I'll be out somewhere and have i on shuffle and i 'll get several good songs.then comes a song that totally messes up your groove and then i have to pull it out and change it.which is not a big big deal but with the smart shuffle you are talking about sounds really good and helpful because i dont have time to edit in song all the time . I'd like it to be on smart shuffle so i know i'ts not going to al of a sudden just pick a song that suck
